摘要
淮南-南京-上海1000 kV交流特高压苏通GIL综合管廊工程是世界上首次将特高压输电工程和隧道管廊结合的重大创新工程。工程具有大直径、长距离掘进、高水压、地质及河势复杂等特点。本文对工程总体设计成果,如平纵断面、横断面布置、隧道结构及特殊地段设计等关键技术问题进行了分析,其设计标准、工作思路、创新理念、建设经验等可为类似工程提供参考。
The Sutong GIL(Gas-insulted Transmission Line)utility tunnel is a great and innovative project,which is a part of the Huainan-Nanjing-Shanghai 1000 kV AC UHV Transmission Line.This project is featured by largediameter and long-distance shield tunneling,high water pressure,complicated geological condition and river regime.This paper analyzes the key technical problems in design of longitudinal and cross-sectional profiles,tunnel structure and special sections of the overall route.The design idea,innovation and construction experience can provide some reference for similar projects.
